Answer: The correct formula for phosphorous pentachloride is 
because a subscript 5 indicates five chlorine (Cl) atoms.
Explanation: For the given molecule, phosphorous pentachloride, there are 2 atoms present which are phosphorous and chlorine atoms.
Number of phosphorous atoms = 1
Number of chlorine atoms = 5
So, the correct formula for phosphorous pentachloride will be because the subscript 5 represents the 5 chlorine atoms.
Answer:
Specific heat is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in temperature.
Explanation:
Answer:
The most reasonable estimate for the O–S–O bond angle in hyposulfite = 106°
Explanation:
Hyposulphite (so₂²⁻) is polyatomic ion .
According to VSEPR model
Total elrctron pairs ![=\frac{1}{2} [V+X -C+A]](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7D%20%5BV%2BX%20-C%2BA%5D)
V = Valence shell electrons of central element
X = No. of monovalent surrounding atoms
C = Cationic charge
A = Anionic charge
Total electron pairs ![=\frac{1}{2}[6+0-0+2]= 4](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7D%5B6%2B0-0%2B2%5D%3D%204)
That is two bond pairs and two lone pairs
Because hidrogen ions in acid and hidroxide ions in base reacts to form H²O. Heat are produced in order the electrons to bond
